Richard Hambelton, known for his lurking shadow paintings on building walls, was not included in the current 1980s Downtown art show at New York Universitys Grey Art Gallery. Recently, Hambelton came into the gallery, checked out where the security cameras were, took out his paint and quickly put up a shadow figure on the wall. There was and still is no mention of Hambelton in the exhibition  but the gallery has not taken down his work.
